Thru-The-Wall Installation
NOTE: Consult local building codes prior to installation, 
or a qualified carpenter.
H Select Wall Location
This air conditioner has a slide-out chassis, so that it can be
installed through an outside wall as specified below:
Heavy Duty (FAS) Median (FAM)
Max wall thickness 12" 10"
IMPORTANT: Side louvers must never be blocked. 
NOTE: All parts needed for Thru-The-Wall Installation are
provided,except a wood *¥ame, shims, and 10 wood screws (#
10-1" long minimum). Select a wall surface that:
1. does not support major structural loads such as the lYame 
construction at ends of windows, and under truss-bearing
points, etc.
2. does not have plumbing or wiring inside.
3. is near existing electrical outlets, or where another outlet 
can be installed,
4. faces, and is not blocked to the area to be cooled.
5. allows unblocked airflow from rear sides and end (outside) 
of installed air conditioner.
Carefully measure and cut an opening with the following 
dimensions depending on your model. See FIGS. land 2.
WIDTH "X" - inside model width plus twice the thickness 
of lYaming material used.
HEIGHT "Y" - inside model height plus twice the thickness
of *¥aming material used.
Heavy Duty (FAS)
Inside Frame Height: 187/d' (47.9cm)
Inside Frame Width: 263_" (67.9cm)
Median (FAM)
18" (45.7cm)
237s" (60.6cm)
FIG. 2
Prepare Wall
1. Prepare wall in frame construction (including brick and 
stucco veneer). Working l¥om inside the room, find wall 
stud nearest the center of area where air conditioner will
be installed (by sounding wall, or by magnetically finding 
nails).
2. Cut or knock out a hole on each side of center stud.
3. Measure between inside edges of every other stud as shown 
in FIG. 1.
FIG. 1
3-3/8" MIN
(8.6 era) ,Q
4. Build a wooden flame with the INSIDE dimensions of
your model listed above.(Measure twice remember...)
Frame depth should be the same as wall thickness. Fill in 
the space l¥om the opening to the studs with wood spacers,
as shown.
5. Nail framd to spacers to spacers with front flush with 
dry wall.
